Title: Incoming display system of automatic exchange
Inventor: FUJII AKIRA
IPC: H04M9/00
Filed: 1982-03-26
Abstract: PURPOSE:To halve the number of incoming section relays and to decrease the man-power of wire laying works from an inter circuit, by flickering an incoming display lamp with a call signal relay in common without using the inter circuit, to distinguish an incoming call from an extension or an attendant board at the  incoming call. CONSTITUTION:A relay A is a relay activated at the incoming call from the attendant board and a relay R is a relay repeating the operation and restoration to transmit a call signal at incoming call. When a call is incoming from the attendant board, the relay A is activated from a signal distributor. The relay R repeats operation and restoration similarly and the lamps (exchange) are  flickered. Further, a ball of a telephone set rings. When a call is incoming from the extension, only the relay R repeats the operation and restoration and the lamp (automatic) is flickered similarly. Through the ringing of the bell and the flickering of the lamp, the call is distinguished as the call from the attendant board or the extension. Thus, since the relay R is used for flickering, the incoming section relay from the extension is eliminated.

Title: Gain changeover circuit
Inventor: TOYOMURA YASUHIRO
IPC: H03G3/30
Filed: 1992-02-03
Abstract: PURPOSE:To make the frequency characteristic flat even when the gain is switched while the gain of a feedback differential amplifier is switched with an electronic switch. CONSTITUTION:The gain changeover circuit consists of a differential amplifier 4, a feedback resistor 6, resistors 7, 8 connecting to a noninverting input terminal, transistors(TRs) 11, 12 and an amplifier 14 used to invert a gain switching signal.

Title: Working method of straightener of metallic pipe
Inventor: TANAKA KENICHI
IPC: B21D3/08
Filed: 1982-03-25
Abstract: PURPOSE:To perform straightener working without deteriorating collapes strength, by passing a metallic pipe through plural-connected rings that rotate in the circumferential direction and giving axis symmetrically distributed load alternately to the outer face of the metallic pipe inside of the rings. CONSTITUTION:Ring supporting positions of supporting rolls 4 are deviated up and down alternately, and the deviation X of the center O' of each ring 3 from the center O of passing metallic pipe 1 is determined. Then, all rings 3 are rotated and the pipe 1 to be worked is inserted from one side of the group of rings at specified speed and passed through the rings. While rotating, the outer face of the pipe is subjected to distributed load due to pressing of the inner faces of the rings 3, and is corrected by bending and compression. In this case, residual stress can be controlled to a level desirable for collapes strength while securing correcting effect by selecting inner diameter DR and deviation X properly.

Title: Intermusic gap detector of record player
Inventor: MORITA YUTAKA
IPC: G11B3/095
Filed: 1982-03-26
Abstract: PURPOSE:To discriminate an intermusic gap from a modulated groove securely, by supplying outputs of plural filter circuits which have cut-off frequencies set according to the intermusic gap width to detecting circuits each having different threshold value. CONSTITUTION:When a signal in a figure arrives at a terminal 1, a filter circuit 21 outputs the signal as it is, but a processing circuit 3 extracts only a low frequency intermusic gap output b1 with a higher level than a threshold value VTH1. A filter circuit 22, on the other hand, extracts a signal B and a processing circuit 32 extracts a high threshold value VTH2. In this case, a low-frequency modulated groove output (c) is lower than the threshold value VTH1 of the processing circuit 31 and an output c' is lower than the threshold value VTH2 of the processing circuit 32, so they are led out from neither processing circuit.

Title: Tractor
Inventor: HASHIMOTO OSAMI
IPC: B62D9/00
Filed: 1980-04-11
Abstract: PURPOSE:To simplify the operation of a tractor and make the tractor capable of a small sharp turn by a method wherein each wheel is provided with a driving mechanism which can raise and lower the front and rear wheels separately, the mechanism being interlocked with a body turning mechanism used to lower the inside of the turning body while it is being turning. CONSTITUTION:If the front wheels 1 are turned beyond the set angle so as to make a tractor body take a turn to the right, for instance, when turning the body, the second switch 14 will be turned on. A pair of the front and rear wheels on the left are lowered up to the stroke end by the operation of a control valve. On the other hand, if the front wheel is operated to make the body take a turn to the left by turning the third switch 15, a pair of the front and rear wheels on the right are lowered in the same way as the case of turning to the right. Thus the operation of the front wheels in excess of the set angle when the tractor is turned allows the inside of the turning body, making possible a small sharp turn.
